Nerve impulses are caused by Potassium (K+) and Sodium (Na+) ions that are located inside and outside of the cell. The structure of the cell membrane is permeable to Potassium but are highly impermeable to Sodium ions. These impulses are transmitted from one nerve cell to the other in very fast series.
A. A person gets out of his mind, he becomes calm then the situation is effective,he doesn't care out about stuff. It's not B or C of course,it could be D. But i think its A.
Answer:
The correct answer is-
4. true
5. Natural selection
6. microevolution
Explanation:
Adaptive radiation is a cycle where living beings diversifying rapidly from a familial or an ancestral species into a huge number of several new types, especially when there are new environmental aspects present such as different habitats and few competitors.
Thus, it is a true statement.
Natural selection is the cycle through which a population or a species of living beings adjust and change over the period of time. natural selection just acts upon the heritable attributes of a population by choosing for advantageous alleles or and in this manner increasing the frequency of these adaptive alleles in the population.
Thus the option Natural selection is correct.
Changes inside a genetic pool from happening to one generation to another is known as microevolution. Allele frequencies in a population may change because of, natural selection, mutation, genetic drift, and genetic flow.
Thus, the correct answer is - microevolution.
Answer:
The fructose-1,6-bisphosphate aldolase refers to an enzyme that catalyzes a reversible reaction, which dissociates the aldol (fructose-1,6-bisphosphate) into the triose phosphates DHAP and G3P. The sequence of events catalyzed by the given enzyme in the correct sequence is:
a) The ketone gets transformed into the imine derived from lysine.
b) Cleavage and deprotonation take place to discharge GAP and enamine components.
c) Enamine gets protonated.
d) The reaction of hydrolysis takes place to discharge DHAP.
Answer:
The cell membrane
Explanation:
The cell membrane, sometimes also known as the plasma membrane, serves as a clear boundary between the inside of a cell and its outer environment.
